I created a Scene Transition that might work. I noticed that the "setFromAboveLightColor" didn't have the standard detail options like "Duration", which would be a nice upgrade for Alice3.

In the updated version I added an Island to the first scene that used an imported image of Sand for the Island Surface. Another Alice3 upgrade might be to allow Ground Paints to be used to skin things like Shapes.

Also note that the upload feature doesn't support the Alice3 .a3p file extension, so I had to zip it.
